Introduction. White spot lesion is a demineralization of the enamel that appears as a white spot on the surfaces of the tooth. The cause of this spot is determined by the activity of the bacterial plaque and it represents the initial stage of a carious lesion. This lesion is a common side effect for patients with fixed orthodontic appliances mainly because of the brackets’ position that favors the accumulation of plaque that ultimately leads to the formation of the white spot.Methods. We conducted a search on a single database, PubMed. “Orthodontic”, “white spot lesions”, “enamel demineralization treatment” and “remineralization’’ were the search terms used. We found 324 articles, but we took in consideration only the ones from the last 10 years, which resulted in 223 articles.Results. The first step after research was article selection: first by scrutinizing the title and secondly by reviewing the abstracts or full texts. The exclusion criteria were: meta-analysis, reviews, original articles regarding prevention of white spot lesions and their prevalence or incidence. We included the articles that seemed relevant for the treatment of white spot lesions, made either on extracted teeth either on orthodontic patients. We found 75 articles to be eligible for this research and we eliminated 5 because of the lack of an abstract or full text and a further 22 were rejected because they did not fit the aforementioned criteria.Conclusion. Although some traditional methods for the treatment of white spot lesions seem to have undesirable results, nowadays with new technologies and thorough investigations in nanotechnology, the eradication of the lesion appears to be short term.

To our knowledge, recent oral health data in Romania is poor, as no comprehensive oral health surveys have been carried out in the last five years. The present cross-sectional oral health survey aimed to assess the dental health status in 6 and 12-year old children from Transylvania, in correlation with their family background, oral-health behavior, and the intake of sweets. The study was conducted on 290 children from nine schools in the Transylvanian region of Romania. The study consisted of the clinical examination of children, recording of data in an International Cavity Detection and Assessment System (ICDAS) chart, and a questionnaire referring to the child’s parental education, frequency, and motivation of visits to the dentist, dental care habits, and the intake of sweets. Our results indicated that the most prevalent ICDAS scores recorded in 6-year-old children were “0A” (p = 0.001464), “03” (p = 0.00366), “05” (p = 0.005563), “06” for rural areas. Restorations were statistically more prevalent in the urban population (p = 0.000076). The ICDAS score for 12-year old children was “03” (p = 0.003614) and prevalent in the urban area. The ICDAS score for the rural area was “04” (p = 0.0056). Comparing dental health status with family background demonstrated a strong correlation for the group of 6-year-old children, and a lack of correlation for the 12-year-old children. The number of dental visits corelated with the parents’ backgrounds, and was higher in the urban population. Frequent hygiene habits (toothbrushing) were statistically correlated with lower ICDAS scores: “04” (p = 0.016482), “05” (p = 0.039127), “06” (p = 0.010785). Eating habits in both age groups were associated with statistically significant differences of “03”, “04”, “05”, “06”, “0A” in the ICDAS score. The obtained results provided clarification on the dental health situation in Romania and the potential risk factors of caries among the population, and therefore it could be used as a starter point for future studies to investigate, in depth, the effects of various variables on cavities found in Transylvanian schoolchildren.

The enamel white spot lesion is a common complication of orthodontic treatment with a high prevalence. This research aims to create an artificially induced white spot lesion, evaluate three different commercial products in terms of visual appeal, mineral reestablishment, and roughness, and determine which material can recover the initial structure. We created an artificially induced white spot lesion in extracted teeth. The materials used in the study were peptide p11-4 (CurodontTM Repair, Credentis AG), bioactive glass toothpaste (Biomin F, BioMin Technologies Limited), and local fluoridation (Tiefenfluorid, Humanchemie) in conjunction with low-level laser therapy (LLLT). To objectively assess the surface, the roughness, mineral content, and esthetic were measured. The roughness increased with a median difference of −0.233 µm in the bioactive glass group; the color parameter delta L decreased dramatically with a median difference of 5.9–6.7; and the cervical third increased the Ca-P mineral content above the starting stage. Each material contributed significantly to enamel consolidation, with peptide therapy providing the most encouraging results.
